声音在Android设备上无效。 在模拟器上正常工作

Question

I have tried changing the sound scheme several ways. I have looked into Uri and SoundPool but I'm not sure I was using them right. Here is the working code with MediaPlayer:

 final Context context;
 MediaPlayer media;

 void play()
{

 media=MediaPlayer.create(context, R.raw.soundFile);
 media.start();
 }

As I said it runs fine on the emulator. It is an ogg sound file, but I have tried mp3 and wav.

Here is the log file for the crash:

Until now I had not noticed "E/AndroidRuntime( 981): FATAL EXCEPTION: main E/AndroidRuntime( 981): android.content.res.Resources$NotFoundException: File r es/raw/ouch.ogg from drawable resource ID #0x7f040000 ", which is indeed the error I was looking for. I am open to suggestions on a quick fix. Until then I will continue debugging.

Answer 1

Providing the LogCat record of the error would help immensely. Also, try looking at the error log generated there and see if u can spot a 'Caused by' tag and read the relevant error message which should point you to the line number in a file that the error is being flagged at.

(Edit: can you see if u spot any user created files in the log since the log is out of focus and I can't see the whole thing)
